RADIATOR-REPAIR DEVICE.

Application filed March 12, 1917.

To all whom it may concern:

Be it known that we, ELZIE I'I. FIsHnR and VVILLTAM H. FoYE, citizens of the United States, and residents of the city of Seattle, county of King, and State of Washington, have invented certain new and useful Improvements in Radiator-Repair Devices, of which the following is a specification.

Our device relates to a repair device which is intended for use on a type of radiator which is employed in connection with internal combustion engines, and particularly such as are used onautomobiles.

The object of our invention is to provide a repair device which may be used to stop leaks, which may have been produced by accident or otherwise, in radiators of this type whereby the continued use of the radiator and the engine may be secured.

Our invention comprises the combination of parts which will be defined in the claims.

In the drawings, Figure 1 is a side elevation of an engine with a portion of the easing broken away to show the location of our repair device when the same is put into use.

Fig. 2 is a front elevation of a portion of the radiator of an automobile showing our device in place thereon.

Fig. 3 is a section through a radiator showing our patch applied.

Fig. 4 is a horizontal section through a portion of a radiator of slightly different shape showing a special form of patch designed for use thereon.

Our device is designed for use with radiators of that type which are ordinarily known as the honeycomb type. These radiators consist of a chamber, usually of relatively small thickness, containing front and rear parallel walls through which are formed a multitude of passages, throughwvhich the cooling air passes. In such radiators the liquid circulates about these tubular passages and the air passes through them.

In such radiators leaks are apt to occur due to accidents, such as contact with some object, which ruptures the wall or, due to gradual giving away. Whatever may be the cause of the leak, unless this is repaired and stopped, the water will run out of the radiator and, in consequence, the water circulation of the engine is destroyed and it is impossible to operate the engine. In consequence, such a leak without means for repairing it, means the abandonment of the Specification of Letters Patent.

operation of the engine. Such result is sometimes the cause of serious trouble.

By the use of our device a leak of this character, unless extremely serious, may be repaired so that the engine may be operated until it can be taken to some point where repairs may be made. In fact, the operation of the engine may be continued indefinitely.

Our device consists of two plates 1, of metal, preferably iron or steel, and also preferably of relatively thin stock. For this purpose one-eighth of an inch will in many cases be found suflicient, although in some cases rather heavier stock may be needed. Associated with each of these plates is a gasket, or packing plate 2. This may be made of ordinary rubber, as for instance, a piece of an old tire, or of any material found suitable for such purposes. In case of necessity it would be possible to use several layers of cloth.

The iron plates 1 are provided with a series of holes 10, located close to their outer edges. The gasket 2 should be provided with holes located to correspond with such holes in the iron plate 1, as are employed for securing the patch in place, except in case a gasket small enough to fit within the bolts is large enough to cover the leak. When a leak has been produced in the radiator, two of these plates are used with their corresponding gaskets, one plate being applied to the front surface of the radiator and the other to the rear surface thereof in such position as to inclose the injured section of the radiator.

Bolts 3 of such size and length as to pass through the air circulating passages in the radiator and through the plates 1, placed upon the front and rear surfaces thereof, are passed through the holes 10 in the plates and the passages in the radiator. These bolts are then tightened so as to clamp the patches upon the front and rear surfaces of the radiator. These patches will close the ends of a certain number of the air passages and, while the water from the radiator may leak into such passages as may communicate with the rupture which has occurred, this water can not be discharged, because the patches close the outer ends of such passages. In consequence, the water will not be discharged and the radiator may be con tinued in use. The result thus is limited to the cutting out of action of merely a small section of the radiator, leaving the remainder of the, radiator effective for cooling purposes. In consequence, the engine may be continued in action and the repair of the radiator may be postponed until such time as it may be convenient to make the repair.

lVe have found by experience that the exact spacing ot the holes in the patch is not material. It is however, possible to shift the patch into positionso that at least four bolts may be used to secure the same in place.

lVhat we claim as our invention is:

1.' A repair device for injured radiators having alternate air passages and water chambers, comprising a pair of patch plates and gaskets therefor, said patch plates being of such size as to overlap a plurality of the air passages each' of said plates having a plurality of bolt holes formed therein and bolts adapted to pass therethrough, said bolt holes being located in such spaced relation in the plates that when the device is in position said bolts lie upon opposite sides of the part to be repaired and pass through some of the air spaces not affected by the injury.

2. A repair device for injured radiators having alternate air passages and water chambers, comprising a pair of patch plates Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
